Abstract ：
Since the winding and permanent magnet of bearingless flux-switching permanent magnet motors are located on the stator, the composition of the air gap magnetic field is complicated, which makes the mutual coupling problem of suspension and rotation of the motors prominent, causing the control performance of the suspension and rotation to be affected. Therefore, based on the rotor dynamics model, a decoupling control strategy based on finite element analysis (FEA) and linear active disturbance rejection theory is proposed. First, according to the structure of the motors and the FEA results, the stiffness matrix of the motor suspension plane coupling itself and its coupling with the rotation plane was obtained. Then, through rotor dynamics analysis, the kinematics model of the suspension system was obtained. Furthermore, the coupling stiffness matrix is combined with the active disturbance rejection theory to construct a decoupling control strategy for online self-tuning of key system parameters. The simulation and experimental results show that the proposed scheme has good dynamic performance and robustness while ensuring the precision of suspension control.

Abstract ：
Aiming at the problems of inaccurate model, coupling of identification parameters, and low identification accuracy in the identification of permanent magnet synchronous linear motor (PMSLM) mechanical parameters, a mechanical parameter identification algorithm based on transmission model reconstruction was proposed in this paper. First, an extended state observer was established based on the reconstruction model to obtain the coupling information of the mover mass and friction force, electromagnetic thrust and initial value of mass identification. Secondly, in order to eliminate this coupling, a two-stage mover mass decoupling identification strategy was proposed. Thirdly, according to the friction characteristics of PMSLM, a friction force model that comprehensively considers the effects of velocity and acceleration was constructed to describe the real friction force more accurately. Finally, a control system based on the mechanical parameter identification algorithm was built, and the effectiveness of the identification algorithm proposed in this paper is proved by simulation and experimental verification. ©2024 Chin.Soc.for Elec.Eng. 1597.

Abstract ：
A permanent magnet synchronous linear servo motor has the characteristics of high thrust density, high efficiency, and fast control response. It is widely used in rail transit, intelligent manufacturing, and aerospace fields. The electrical or mechanical parameters of the motor and nonlinear resistance interference will affect the high precision control of the linear servo. Therefore, the stable and efficient displacement control algorithm has important engineering application value to improve the system performance. Servo control can be divided into serial and parallel systems according to the relative position of displacement and velocity loop. However, whether serial or parallel control, most controller parameters need to be set in advance and are generally fixed, and adjusting the actual control effect is impossible. This paper proposes a parallel control strategy of variable parameter displacement velocity of permanent magnet synchronous linear motor based on composite neural network reconstruction object, which realizes the high-performance control of linear servo motor. Firstly, a parallel controller with variable parameters is designed using the error information of the moving displacement and linear velocity. Then, the displacement output of the permanent magnet synchronous linear motor is reconstructed by a composite radial basis neural network containing multi-dimensional information of the control object, and the partial derivative of the displacement to the control signal is obtained. Finally, based on the closed-loop stability condition of the system, a complete parameter update strategy of parallel controller with displacement velocity is provided according to the comparison between periodic retrieval errors and control targets. In the experiment, a permanent magnet synchronous linear servo system is designed, and different network observations, position controls, and object parameter controls are compared. The network comparison shows that the composite radial-based neural network has fast observation speed and high observation accuracy, and the observation time and root mean square error are 18.63 μs and 0.063 mm, respectively. The position control comparison shows that the variable parameter parallel algorithm has higher control precision than the fixed parameter algorithm, such as PID control, with a 30%～50% improvement effect in the displacement and velocity control error indexes. The parameter control comparison shows that in the variable parameter parallel control strategy, when the moving mass changes, the root mean square of displacement error is less than 0.015 mm, and the absolute maximum error is less than 0.060 mm, which means that the algorithm has stability and universality. The following conclusions can be drawn: (1) The composite RBF neural network structure has better observation performance than the traditional RBF neural network. Compared with the traditional improvement method, it has a better effect with less computing pressure on the processor. (2) Compared with the fixed coefficient algorithm, such as PID, the proposed variable parameter parallel control strategy can effectively improve the control performance of the actuator displacement. (3) The variable parameter parallel control strategy can guarantee the high precision control effect under different displacement settings and object parameters. © 2024 China Machine Press.
